Abstract

Flow slides can play an important role in the stability of coastal foreshores and structures, in harbour design, in dredging activities and placing of hydraulic fill structures. In the south western part of the Netherlands the phenomenon is of major concern for the protection against flooding by means of dikes. More than 1100 slides have been registered since the year 1800. In the paper the practical experience and the knowledge obtained from experiments and fundamental research is briefly summarized. An engineering approach to coastal flow slides that combines the Dutch experience with flow slides with results of fundamental research of the past 10 years, is described.
